MMRP PA – Historic Potomac River Ranges

In support of a MMRP Preliminary Assessment (PA) for the Naval Support Activity South, Dahlgren, OHI was tasked with conducting an archival research effort to identify and map former / historic ranges within the Potomac River and its tributaries. Although the project was conducted for the Navy, the scope included all DoD Services / installations and Formerly Used Defense Sites with a history of munitions activities within the water.

OHI’s scope included conducting research at the National Archives and the Navy Yard in Washington, D.C as well as researching available historical records at the various installations along the Potomac.
